DFL_FPGA_PORT_ERR_SET_IRQ(9)

💅 DFL_FPGA_PORT_ERR_SET_IRQ(9) 💅

okay so bestie, welcome to the Kernel API Manual — this is a page about one very specific little ioctl, and honestly? it's giving "niche but iconic." let's get into it 🫶

---

✨ NAME ✨

DFL_FPGA_PORT_ERR_SET_IRQ — literally this ioctl right here:

_IOW(DFL_FPGA_MAGIC, DFL_PORT_BASE + 6, struct dfl_fpga_irq_set)

no cap, that's the whole name section. it's an _IOW, it lives at DFL_PORT_BASE + 6 under DFL_FPGA_MAGIC, and it takes a struct dfl_fpga_irq_set. periodt 💅

🦋 SYNOPSIS 🦋

DFL_FPGA_PORT_ERR_SET_IRQ

yep. that's it. that's the synopsis. she's short and she knows it ✨

---

🌸 DESCRIPTION 🌸

so here's the vibe check 💖 — this ioctl is your girl for telling the fpga port error reporting interrupt trigger what to do:

• if evtfds[n] is valid, you're setting the fpga port error reporting interrupt trigger 👑
• if evtfds[n] is a negative value, you're unsetting the related interrupt trigger 🙈

that's the whole personality: valid evtfds[n] = set, negative evtfds[n] = unset. iykyk 🧚

💀 RETURN 💀

• 0 on success 🎀
• -errno on failure 😭

like, the classic. the standard. the main character energy of return values fr fr.
